Patented. June 14, 1932 UNITED STATES PATENT OFFICE RUSSELL W.BORROWDALE, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THEJOGGER MANUFACTURING COMPANY, A CORPORATION OF ILLINOIS AUTOMATICJ'OGGER Application filed February 7, 1928. Serial No. 252,662.

My invention relates to automatic jogging devices, and it has particularrelation to devices of the character indicated wherein joggin mechanismfor accurately and neatly sta ing papers iled one on top of the othermay be actuated y means which at thesame time rovide for the propervertical positionfthe stack.

ore particularly, my invention embodies means for actuating joggingmechanism, that is to say, mechanism whereby a plurality of superim osedsheets are constrained to be stacked in a neat aligned manner in a pile.My invention at the same time provides for a vertical disposition ofsaid pile in accordance with predetermined requirements so that as thejogging mechanism operates to stack the pile the actuating means at thesame time lowers or raises the pile, as the case may be, to receive thesheets as they are placed on sand ile.

p In the embodiment of my invention hereinafter described I have shownit as used to receive sheets or other like articles fed into a pile froma conveyor, said conveyor being adapted to carry such sheets or articlesfrom a printing press or the like.

While I have described for purposes of illustration my improved joggingand stacking devices as so used, it is to be understood that suchdescription is not restricted in any sense but is merely for purposes ofillustration.

Broadly speaking, my invention comprises a table upon which the sheetsare to be stacked, together with a back or barrier against which thesheets move to obstruct their forward motion. Positioned on the sides ofthe stacked sheets and capable of being set to accommodate sheets ofvarying widths are what may be termed joggers, that is to say, means forlightly moving to and fro against the sides of the sheet whereby saidsheets are accurately aligned with respect to their side edges. Inasmuchas the aforesaid barrier or front piece limits the forward movement ofthe sheet, this means thereby insures an accurate neat stack of sheetson the aforesaid supporting table.

The aforesaid jogging or stacking apparatus is synchronized orcooperatively associated with a lowering mechanism so that asthe'jogging is performed the supporting table is lowered to apredetermined degree, thereby insuring a correct positioning to receivethe sheets as they are fed on the stack by the aforesaid conveyor.

My invention may be better understood with reference to the detailsthereof in connection with the accompanying drawings, in which:

parts being shown for purposes of simplicity and clarity.

Referring now more particularly to the drawings, my invention embodiesprimarily two adjacent vertical standards tied togcther by tie rods 10aand which are provided with opposed channel portions 11, which channelportions receive bearing portions 12 of table receiving arms 12a and12?) which latter are adapted to carry up and down astack-supportingtable 13. It will be noted that this table is in the form of a truckwhich may be attached to and detached from the arms 12a and 12?) bymeans of the spring catches 12c and 12d on said arms. This permits aheavy stack of paper to be handled most expeditiously.

The table arms 12a and 12/) are supported in their vertical movement bychains 14a and 1 14!), which chains are fed over sprockets 15a and 15?)mounted on a shaft 16. the latter being journalled in side pieces 17 and18 of a gear box 19 and the upper portion of one of the standards. Saidbox is illustrated more 7 in detail in Figs. 7, 8 and 9. Said chains areprovided with counter-balancing weights 14c and 14d.

Secured to the upper ends of the standards 10 is a. frame comprisingside pieces 21 tied together at their outer ends by a member 22. Mountedon said frame are the jogger members, that is, those members which aremoved against the edges of the paper at the top of the stack to insureproper alignment of said paper. These jogger members comprise parts23'24 to engage the sides of the sheets and a forward plate 25, whichmembers 23, 24 and 25 are jogged against the edges of the sheets as theyare stacked by the mechanism which will be hereinafter more fullydescribed.

A stationary plate 26 is arranged to stop the forward movement of thesheets. Said plate 26 is attached to a rod 27 to permit of adjustment,the rod 27 being secured in adjustable relation to the backframe piece22 sheet. After said plate is moved to accommodate such an over-sizedsheet it is again moved back to correct aligning position by the actionof said spring 26a and the limiting of collars 267) and 260.

An actuating member 29 is arranged as shown in Fig. 1 to be moved fromsome toand-fro moving member on the press or other device with which mystacking apparatus is associated. Said member 29 is secured to and movesa pivoted arm 30. The arm 30 is to said jogging rods 33 and 34 and areeach provided with an actuating slot 37 to receive pins 38. Said pins 38are secured to members 39, which latter are attached to the backs of theside plates 23 and 24.

Said pins 38 extend upwardly into slots 40-40 in the bearing portions.35 so-that when the jogging rods 3 3-34 move to-andfro, the action ofthe slanting slots 39 and the pins 38 cause the members 40-40 to moveperpendicularly to theedges of the paper and thus jog plates 23 and 24against the edges of the sheets of paper as the latter are fed into thetop of the stack. The forward jogger 25 is secured to said rods 33-34 bya connecting member 25a. so that said part 25 is also synchronouslymoved to align the sheets, it being noted that the sheets, as they comefrom the conveyor are fed over said jogger 25 and into the stack and arethen jogged in four mutually perpendicular directions.

One of the side jogging rods 34 actuates through a pin 34a and a slot41a a pivotally mounted pawl-carrying arm 41, said arm 41 being mountedaround a shaft 42, the further purpose of which will be hereinafter morefully described. As the rod 34 moves the lower end of said arm 41, apawl 43 pivotally mounted on the upper end of said arm engages withteeth 44 on a rotary or circular ratchet member 45 and moves the latterand the shaft 42. The number of teeth which said pawl 43 may engage, andtherefore, the amount of movement imparted in step-bystep manner to thegear 45, may be predetermined by the correct positioning of a shroud 46which is positioned over the teeth on the ratchet 45. This shroud isapertured to permit the projection therethrough of the teeth 44, asshown, and may be rotarily adjusted in any predetermined position bybeing moved against the action of a spring biased catch 47.

Secured to the same shaft 42 as that upon which member or circularratchet 45 is mounted is a bevel gear 48 which, in turn, meshes withanother beveled gear 49. Said gear 49 is secured to a shaft 50 carryinga worm 51, said worm 51 meshing with a gear wheel 52 which is secured tothe same shaft as that upon which the sprockets 15a-15b are described,the chains 1414 are fed to permit the table to move downward.

From the above it will be apparent that I have eventuated a new andnovel jogger and table positioning apparatus in which the joggers andthe table-lowering mechanism are actuated from a common source in anefficient and expeditious manner.

The worm is spring biased to the right so that a manual turning of thegear 52 in a direction reverse to the normal pitch forces said worm outof engagement and permits the rapid movement of sprockets 15a and 15band the chains 14a and 14b to elevate said table. Spring 51a providesfor such disengagement upon the movement of a handle 53 and theengagement of clutch comprising parts 54a and 54?). The pushing in ofsaid handle connects parts 54a and 54b whereupon rotation of the handle53 rotates said shaft.

Another direct movement of the table is provided for by mounting anout-board gear 55 on shaft 42 and a gear 56 on shaft It so that pullingout of handle 53 engages said gears 55 and 56 and permits directmovement of beveled gears 48 and 49 to raise or lower said tablemanually.

As before indicated, the table can be gradually lowered in synchronizedrelation to the feed of sheets to the stack, the said sheets beingjogged into a neat and accurate pile as they are fed to the table. Whenthe table is full the spring catches are disengaged'and the table rolledoff the arms. This particular combination is of great importance in thedesirability of my device.

I also provide a novel receiving means to be carried on the table whenbooklets and envelopes or like articles which are thicker at one edgethan the other are to be stacked. Said means comprises an open front box60 having a biased piece 61 in the bottom thereof which piece may beadjustably secured in the bottom of the box by holding means 62adjustable along slots 63 in the side of the box to insure even stackingof articles having one edge thicker than the other. The piece 61 is soarranged that the articles are fed into the case with the thicker edgesadjacent the lower side of the piece with the result that the topmostarticle in the stack will be substantially horizontal, as indicated indotted lines.

While I have described but one embodiment of the elements whereby mynovel invention is practiced, it will be understood that the same isillustrative only of the principles which I hereafter claim, and Idesire therefore. that my invention be limited only by the said appendedclaims or the showing of the prior art.
